Multivariate Behavioral Research, 1977
Two articles on canonical correlation are criticized as erroneous, Wood (1972) and Nicewander & Wood (1974). In both instances, the errors would have been avoided had the authors been required to offer both the mathematical basis of their contributions and illustrative worked examples.

SUMMARY Various extremal results have been proved concerning the efficiency of least squares estimates relative to Gauss-Markov estimates and concerning the canonical correlations between two sets of random variables. In this paper we show how these two types of result are related, and derive a new result from which many previous inequalities can be ...

SSRN Electronic Journal, 2011 We introduce an ordinal model of efficiency measurement. Our primitive is a notion of efficiency that is comparative, but not cardinal or absolute. In this framework, we postulate axioms that we believe an ordinal efficiency measure should satisfy.

Economics Letters, 1991
Abstract We study speculative behavior in a stochastic overlapping-generations model and we show how the link between the existence of bubbles and dynamic inefficiency, which has been established for the deterministic case, is broken when risk-related factors, such as risk premia and capital gains, are explicitly taken into account.

Pareto-improving inefficiency [PDF]
Oxford Economic Papers, 2010 This paper considers a simple moral hazard setting in which a project owner (or, more generally, a principal) hires a contractor (or, more generally, an agent) to operate her project. We show that a systematic increase in the agent's operating costs can increase either the principal's profit or the agent's profit. The combined profit of the two parties

Inefficient Liquidity Creation
SSRN Electronic Journal, 2018We present a model in which intermediaries create liquidity by issuing safe debt. There are two types of intermediaries: Traditional banks create liquidity by issuing equity and holding assets to maturity. In contrast, market-based intermediaries create liquidity by selling assets in fire sales in downturns.

Sources of Intellectual Inefficiency
Psychological Reports, 1971This study examined the relationships among IQ, education, and intra-subtest scatter on the Wechsler Adult Intelligence Scale in a sample of schizophrenic patients. It was predicted that scatter would be greatest in Ss having high IQ and low educational level and in those having a low IQ and high educational level.

The Inefficiency of Least Squares
Biometrika, 1975SUMMARY Two criteria are set up to judge the relative performance of the least squares estimator and the best linear unbiased estimator of , in the linear model y = X/, + u, where E(u) = 0, E(uu') = F. The matrices X and r are found so that the relative performance of least squares is worst.

The dynamic inefficiency of capitalism
Journal of Political Economy, 1973A new paradigm for capitalism is woven from Marx's dynamic conflict and Keyne's disjunction between the saving and investment decisions, in which capitalism is viewed as a differential game between workers, who may save or consume, and capitalists, who may consume or invest.

Sustainable Investing: Navigating the Inefficiencies of an Inefficient Market
2022Over the past decade, sustainable investing, also known as socially responsible investing, ethical investing, or responsible investing, has experienced heightened popularity worldwide. This popularity reflects the increasing awareness of investors of social, environmental, ethical, and corporate governance issues.
